ECC85 CVC Chelmer Valve

Description

Compact Dual Triode for RF Circuits
The CVC Chelmer ECC85 is a miniature double triode vacuum tube designed specifically for high-frequency circuits like FM tuner front-ends and oscillator stages. It includes two matched triode sections in a single glass envelope. This layout supports balanced signal processing and clear, low-noise amplification. Because of its compact format and precise electrical behavior, the ECC85 is widely used in vintage radio repairs and custom RF applications.

Consistent Gain and Oscillator Stability
Each triode section delivers strong, reliable gain while keeping distortion minimal. Moreover, the ECC85 handles VHF frequencies with ease, ensuring stable reception and clean signal transfer. CVC Chelmer’s high-quality manufacturing minimizes capacitance and reduces microphonics. Therefore, oscillator circuits stay stable even during extended use. Unlike lower-grade alternatives, this tube resists drift and maintains performance in continuous-use environments.

Flexible Format and Broad Compatibility
Fitted with a standard 9-pin B9A base, the ECC85 installs easily into most radio chassis and RF test rigs. Additionally, it directly replaces other ECC85 types from various manufacturers. Whether you’re restoring a mid-century receiver or building a boutique preamp, the CVC Chelmer ECC85 integrates smoothly into your project.

Durable Build, Trusted Quality
Chelmer tubes are known for dependable construction and consistent electrical output. The ECC85 exemplifies this legacy with rugged internals and tight quality control. Furthermore, it holds gain and noise specs reliably over time, even under repeated thermal cycles. As a result, radio technicians, hi-fi builders, and RF enthusiasts choose this model for serious applications.

Ideal for Vintage and Modern Designs
Whether you need stable oscillator function or clean signal amplification, the CVC Chelmer ECC85 delivers. It provides compact size, strong gain, and smooth, low-noise output. Thus, it stands out as an excellent choice for RF engineers and hobbyists alike.
